Bug 780016 - Conversion path between nonpremultiplied formats ...

.. may pass through a premultiplied format, losing color information
of fully transparent pixels

Add a few pixels with zero alpha to the test pixels array, to penalize
such paths.  16 pixels seem to be enough for the conversions tested,
using the default tolerance.

Add a regression test.
